EMMET NICHOLS, OF PARIS, ILLINOIS.

HEATER FOB STOCK-WATERING TANKS.

Application filed November 26, 1921. Serial No. 517,845.

To all whom it may concern:

Be it known that I, EMMET NICHOLS, a citizen of the United States, residing at Paris, in the county of Edgar and State of Illinois, have invented certain new and useful Improvements in Heaters for Stock- Watering Tanks; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art'to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in heaters, and more particularly stated contemplates the production of a portable heater arranged, and adapted to effect the circulation of water, such for example, as that used in stock watering tanks. 7

An object of the present invention is to provide a compact and readily handled heating device which can be positioned in an animal watering tank to prevent freezing of the water in winter weather.

Another object of my invention is the production of a self-contained heating unit embodying combustion chamber, grate, ash pan, and associated water circulating pas- :sageway through which latter the water is caused to pass as the temperature of the water rises.

A further object of the invention is to produce a'comparatively simple and easily cleaned portable heater, which can be inexpensively manufactured.

A still further object of the invention is 'to design a heater of a shape and size capable of relatively long and eifective periods ofusein extremely cold weather.

Other objects will in part be obvious from the specification and appended claims, ref

erence also being had to the accompanying drawings, in which 1- Figure 1 is a vertical sectional view through my improved heater;

Figure 2 is a top plan View thereof with the lid removed; I

Figure 3 is a vertical sectional view of the container or bowl; and

' Figure 4 is a top plan view of the ash receiver or pan.

Referring to the drawings in which similar reference characters designate corresponding parts in the several views, the

heating apparatus comprises a container or bowl formed with supporting legs or base 2, a compartment 3 for the reception of the ash receiver, and the chamber 4, termed l01 purposes herein, the combustion cham- The container 1 is preferably cylindrical in cross section, being provided with a draft passage 5 at one side thereof, and open at the top as shown for the reception of the lid 6. The chamber 4 is of a size sufiiciently large to permit relatively slow but ample combustion.

In the combustion chamber 4 and more particularly at the lower portion thereof, I arrange a coil 7, said coil being adapted to form a water circulating passageway 8. The coil 7 is of standard pipe having at each end elbow fittings connected to the respective inlet and outlet pipes 10 and 11. The inlet and outlet pipes or nipples extend through openings in the walls of the container, and asbestos or other water-tight washers 12 are positioned around said pipes and held in place by nuts 13 to prevent the leakage of any water into the containerl. The inlet pipe 10 is located relatively close to the bottom of the combustion chamber and is designed to be always immersed in the liquid to be heated. The outlet pipe 11 is preferably located upon the opposite side of the container above the inlet openings. I have shown four coils of piping in the present embodiment but it will be understood that various other lengths, sizes and shapes of pipe orother conduits cast or otherwise, may be substituted to provide a suit-able water circulating passageway.

I prefer to use the coil 7 so as to obtain maximum efliciency from the heat in the combustion chamber, and at the same time afford a simple construction which can be readily inspected and repaired.

The grate 14 is positioned within the coil 7 and is in the form of a circular frustoconical basket provided with an annular wall having slots 15 and a bottom having slots 16. The material to be burned is positioned within the basket and a constant and ample draft. is obtained through the aforesaid slotted portions.

The grate is designed to be supported upon the ash receiver 17, and more cs pecially upon the inwardly projecting fins the watering tank.

18 clearly shown in Figure 4:. These fins are designed to support the grate at a height approximating the top otthe ash pan (see Figure 1). i

The ash receiver or pan 17 is frustoconical and circular, and of a diameter sufficiently large to receive the ashes from the fuel consumed in the grate 14. A handle 19 is provided on the ash pan, and as shown may be cast integral therewith. The com-- partment 3 which receives the ash pan is formed to readily receive the ash pan and the flaring. of the walls of the casing at the top of the said compartment 3 permits of the-easy depositing of the ash pan therein.

The lid 6 is formed with a depending flange 20 which fits within and against the inner face of the cylindrical wall of the container. A shoulder 21 is provided centrally of the lid and is adapted to receive a. stove pipe with ventilator top and cap (not shown) to keep out rain and snow. Handles 22 are provided on the lid. 7

V Handles 23 are also provided on the container 1 as shown, for facilitating the handling of the heater. The handles are formed of bent rods, the'ends of which are threaded and receive nuts upon the inside and outside of the container and lid, as

shown.

. In assembling the parts of the heater, the ash pan is first lowered into the compartment 3. The grate 14: is then filled. with burning coal or other fuel and lowered until it rests upon the fins 18 of the ash. pan. The lid 6 is then fitted in place, and the heater is now partially submerged into It will be noted that the extension provided on the lid serves as a damper for the upper end of the draft passage 5. In practice the inlet opening 10 is submerged beneath the level of the water. The outlet opening 11 may or may not be wholly submerged, it being desirable, however, to submerge the outlet in order to obtain a proper circulation of the water.

When a sufficient temperature has been reached the water will circulate through the inlet 10 into and through the coil 7 and out the pipe 11. It is this circulation of the water in freezing weather which prevents the freezing of said water, thereby insuring drinking water for the stock. The quantity of fuel may be varied to provide relatively long or short heating periods, the draft 5 and opening at the bottom thereof serving to produce a down draft. The opening 21 forms the outlet passageway for the escape of the smoke or products of combustion. 7

Changes within the scope of my invention may be made and I do not wish to be understood as limiting myself to the exact construction herein set forth.
